Default Listen to me now and believe me later: Sensors

If you turn off all the new sensors (compared to S3) you should notice none- or a lot less of the apparent lag issues and the good battery life should be even better. Most of the new sensors IMO are fluff, but appreciate some may love them and even need them.

That pretty much goes without saying. Sensors still use power.

this is good advice. the new features are cool, but most of them will be a novelty and i most likely won't be using them on a daily basis anyway. there are probably a lot of users that don't know these bells and whistles use power. if users can get a few extra minutes or more by disabling them then no harm no foul.

that said, samsung did make it easy to disable the novelty features by providing access directly from the notification pane rather than burying them in the settings somewhere.

disabling some of the other sensors may be more involved, but disabling most of the new features like air view and air swipe, etc.

Sensors are used when you use any of the motion features, like turning your phone over to mute, tilt to zoom, tap top to jump to the top of the page, smart stay etc etc...

I might turn off a few features after a while but going to use it a few weeks to actually see how the battery life is and what all the S4 can do.

I have pretty much charged any phone I had (Evo, S3, EVO LTE, iPhone's, Treo's, Palm Pre) every night with an occasional 1.5 - 2 days. As long as I can get from morning until I get home, I am fine.

Everything the phone responds to is the result of sensors:

Ambient light sensor: screen brightness
Gyroscope: screen orientation
Touch screen: touch sensor
Shut off the display when you put the phone to your ear: proximity sensor
Hygrometer: humidity sensor
Thermocouples: battery, CPU, and ambient air temperature

Et cetera and so on...

Please note I stated all sensors that are new compared to the S3 and not all sensors. Simply put, the sensors while active poll the cpu, based on firmware and system settings and provide info to the device.

Thank you for the information. By the way, do you or anyone know the battery life with the sensors on vs sensors off?
i'll probably want to play with some of the neat-O-features but like some of you i'll probably turn them off eventually.

What app can be used to disable the individual sensors (outside of the notification center)? Does the phone have to be rooted to do so?

Also, is there a listing as to which sensor controls which functions? Would hate to disable something that backfires and I can't use the phone.

I do not think so.... I would not know the chipsets gating design, or the firmware ability to call them or the sensors. I could, but have no desire to read the tech docs for the chips. I am a user not a maker

Added:

There looks like there are several top level sensor settings to disable in settings. This could be a quest for rooting efforts as far as specific sensors- assuming there is access at firmware level.

I'm seeing some sluggish behavior when pressing the Home button to go back to the launcher screen. Is anyone else seeing this?

My guess is the things mentioned by posters here, sensors, animations and if the Samsung voice can be disabled, that will all yield efficiency. Of course, some will say what is the point of the features then? IMO, there really is not one overall other than bling and marketing gimmicks. A few or all could be handy to other folks, but handy to know that things can be turned off if you do not want the stuff.

Alright, I got there and disabled a few things included S-Voice which may be cool to use but mostly useless for me.

Default What methods has everyone taken to conserve battery life?

I'm just curious as I noticed a 10% battery decrease within an hour last night when I wasn't even using it. I currently have the default settings. Although I did increase the screen timeout to a minute. Mind you, I always turn the screen off while I'm not using it.

One of the biggest ways to save battery life would be to turn off all of the special software features Samsung includes. Air View, Smart Scroll, etc.

Also turn off NFC and Bluetooth when you are not using them. I usual turn off auto-sync data too, since I really don't get emails that I must know of immediately.

I'm not sure if juice defender is helping me that much. My brightness is all the way down, notifications are off for the most part and I'm only really texting a small bit. Battery still drops substantially I think.

It varies for me. I had an hour and a half call today and used it for moderate web browsing and frequent texting. It's been unplugged for 5 hours. The percentage is currently 37%.
